Composition and Characteristics of Solid Waste in Sanitary Landfill of Warinchamrap Town Municipality, Ubon Ratchathani Province

Abstract

This research aims to study the composition and physical characteristics of municipal solid waste brought to be disposed of in the sanitary landfill of Warinchamrap town municipality, Ubon Ratchathani province, during the dry season in March 2022. Waste samples were taken from four municipal waste collection trucks in the urban area: Ubon Ratchathani municipality, Warinchamrap town municipality, Det Udom town municipality, and Jaeramair town municipality. The waste composition was studied by the quartering method. The study results were presented with percentages. The results showed that the average density of solid waste within the environmental conservation project was 205.67 kg/m³. The most common component of solid waste is food waste, representing 35.69 percent, followed by waste plastic representing 35.06 percent. The overall moisture content of solid waste was 16.67 percent, with the most moisture content being wood, equal to 41.42 percent. When the plastic waste was sorted for composition, the most LDPE plastic was found at 32.90 percent, including plastic bags and stretch plastic, followed by other types of plastic, such as snack packets and instant noodle packets. Therefore, municipalities in urban areas should focus on waste management at source in terms of food waste and plastic waste according to the 3R (Reduce, Reuse, Recycle) principle. For other types of plastic that cannot be purchased or recycled, there should be a collection system to gather and deliver to be further processed into energy.
